Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in detail.
The present embodiment provides a kind of pipe arrangement method of cigarette air duct integrated, the pipeline includes cigarette air duct road body 1, cigarette
Air duct shared track body 2, cigarette air duct horizontal combination reinforcing rib 3, cigarette air duct vertical integration reinforcing rib 4, cigarette air duct joint internal overarm support 5,
Upper smoke air duct integral support 6 and lower part cigarette air duct integral support 7, wherein：Cigarette air duct road body 1 disclosure satisfy that flue gas and air exist
Flowing is without revealing in one fixed space；Cigarette air duct shared track body 2 is the isolation road body that flue gas and air is isolated；Cigarette air duct is lateral
Joint reinforcement rib 3, cigarette air duct vertical integration reinforcing rib 4 and cigarette air duct joint internal overarm support 5 ensure cigarette air duct road body overall structure not
It deforms, to the whole joint reinforcement rib of cigarette air duct road body 1 and joint internal overarm support in the present embodiment, it is excellent to have carried out structural calculating
Change, whole cigarette air duct integrated road body is optimized for an integral rigidity part, to prevent heat caused by fluid temperature difference in cigarette air duct
Expansion, solves the problems, such as that previous cigarette air duct is unable to coenosarc；Upper smoke air duct integral support 6 and lower part cigarette air duct integral support 7
It is to integrally install cigarette air duct, to realize the actual motion of system, the cigarette air duct integral support in this programme calculates,
It is the joint reinforcement rib and joint internal overarm support together overall structure calculation optimization in conjunction with cigarette air duct road body entirety, ensures holder support
Point reasonability and safety, the position choosing of supporting point then, only need to be to original using the structural framing after original Boiler Furnace
Structural strengthening is handled, and is no longer needed to build new structural framing again, is reduced structure consumptive material and space.
The embodiment of the present invention is welded based on the road body of pipeline, by the steel plate of external cigarette air duct road body 1 by design drawing
After good, then with internal cigarette air duct shared track body 2 flue gas and air insulated are isolated into flue and air duct.The steel of cigarette air duct road body 1
Between plate, the steel plate of cigarette air duct road body 1 is all made of welding manner with cigarette air duct shared track body 2 and connect；Cigarette air duct is laterally joined again
Reinforcing rib 3, cigarette air duct vertical integration reinforcing rib 4 and the steel plate outside of cigarette air duct road body 1 and sections inner side are closed, cigarette air duct is depended on
Road body 1 welds, and reinforces the rigidity of road body steel plate, and cigarette air duct joint internal overarm support 5 is then that cigarette wind is corresponded to inside flue and air duct
The position both ends of road horizontal combination reinforcing rib 3 are welded, by cigarette air duct horizontal combination reinforcing rib 3, cigarette air duct vertical integration reinforcing rib
4, after the steel plate correspondence of cigarette air duct joint internal overarm support 5 and cigarette air duct road body 1 welds together, a structural framing, road body steel are formed
The selection of plate and shaped steel is chosen after being calculated by structural modeling, is allowed to securely be integral rigid road body, to overcome internal cigarette
The temperature deformation in road and air duct；And upper smoke air duct integral support 6 and lower part cigarette air duct integral support 7 are by cigarette air duct
Structural beams combine with cigarette air duct horizontal combination reinforcing rib 3, cigarette air duct vertical integration reinforcing rib 4, cigarette air duct internal overarm support 5 and " cigarette wind
The steel plate of road road body 1 is connected in a manner of frame structure, and the load of cigarette air duct integrated pipeline is passed with the pattern of structural framing
It passs in this structural beams, it, will finally by the structural beams of this upper smoke air duct integral support 6 and lower part cigarette air duct integral support 7
Entirety is novel, and " " pipeline road body is mounted in the structural beams that the transformation of civil engineering armored concrete is reinforced cigarette air duct integrated.
